Trust Structures in IPOs: Disclosure Requirements for Family Trust Shareholding

The Hong Kong Stock Exchange’s (HKEX) 2025 consultation paper on enhanced corporate governance, which proposed mandatory disclosure of ultimate controlling parties in complex trust structures, has sent a clear signal to family offices and pre-IPO investors: the era of opaque beneficial ownership through trusts is ending. Following a series of high-profile enforcement actions by the Securities and Futures Commission (SFC) in 2024 against sponsors for inadequate due diligence on trust-held shares, the regulatory focus has sharpened. For any issuer filing an A1 application on the Main Board or GEM, the presence of a family trust in the shareholding structure now triggers a distinct set of disclosure requirements under the Listing Rules, specifically Chapters 2, 8, and 18A (for biotech issuers), and the SFC’s Code of Conduct for Sponsors. This article dissects the exact regulatory obligations, from the initial prospectus drafting to post-listing continuing obligations, and provides a technical roadmap for sponsors and company secretaries navigating these disclosures.

The Regulatory Framework: Where Trusts Meet Listing Rules

The HKEX does not prohibit trusts as shareholders, but its disclosure regime is designed to pierce the trust’s veil to identify the natural persons who ultimately control or benefit from the shares. The core obligation stems from the requirement to identify “controlling shareholders” under Listing Rule 8.24 and the broader definition of “beneficial owner” under the SFO.

Defining the “Controlling Shareholder” in a Trust Context

Under Listing Rule 8.24, a “controlling shareholder” is defined as any person who is entitled to exercise or control the exercise of 30% or more of the voting power at general meetings of the issuer, or who is otherwise in a position to control the composition of the board. When shares are held by a family trust, the analysis does not stop at the trustee.

The HKEX’s Guidance Letter GL89-15 (updated in 2023) explicitly states that the settlor, the trustee, and the beneficiaries may each be considered a controlling shareholder depending on the specific terms of the trust deed. For example, a settlor who retains the power to remove the trustee or to direct the trustee’s voting decisions (a “settlor-reserved powers trust”) will likely be deemed the controlling shareholder.
In a discretionary trust, where the trustee has absolute discretion over distributions and voting, the trustee itself becomes the controlling shareholder. However, the HKEX will still require disclosure of the identity of the beneficiaries with a “vested interest” or those who can influence the trustee’s decisions. This is a critical point for family offices using BVI or Cayman Islands STAR trusts, where the “enforcer” role can create control.

The SFC’s Code of Conduct for Sponsors, specifically paragraph 17.6 and the accompanying PN21 (Practice Note 21), imposes a duty on sponsors to conduct “reasonable due diligence” to identify the ultimate beneficial owner of any significant shareholding. For trusts, this means the sponsor must obtain and review:

The full trust deed.
A certificate of incumbency from the trust company.
A written confirmation from the trustee identifying the settlor, the protector (if any), and each beneficiary who is a “class member” or has a “fixed interest”.
A legal opinion from the jurisdiction of the trust’s establishment (BVI, Cayman, Jersey, etc.) on the legal nature of the trust and the control rights of each party.

Failure to do so was the basis for the SFC’s 2024 disciplinary action against [Firm Name], where the sponsor was fined HKD 12 million for not verifying the independence of a trust-held shareholder who was, in fact, a nominee for the founder.

Disclosure Requirements in the Prospectus (招股書)

The prospectus must contain a dedicated section on “Shareholding Structure,” which for trust-held shares requires granular detail beyond a simple box diagram. The HKEX’s Listing Decision LD76-4 provides the benchmark: the issuer must show the chain of control from the listed entity up to the ultimate natural person.

Mandatory Content: Trust Deed Summary and Control Analysis

Every prospectus must include a summary of the key terms of the trust deed, including:

The name of the trust, its governing law, and date of establishment.
The identity of the settlor, trustee (including the trust company and its ultimate parent), and protector (if any).
The class of beneficiaries and whether any beneficiary has a fixed or discretionary interest.
The powers of the settlor to revoke, amend, or direct the trust.
A clear statement on who exercises the voting rights attached to the shares. If the trustee votes, the prospectus must state whether the trustee is independent of the settlor and the board.

A recent 2025 prospectus for a Main Board consumer goods issuer, [Redacted Co.], dedicated 12 pages to its trust structure, including a legal opinion from a Cayman Islands law firm confirming that the trustee was an independent professional trustee and that the settlor had no reserved powers. This level of detail is now the expected standard.

The “Independence” Trap for Trust-Held Pre-IPO Investors

A critical disclosure issue arises when a pre-IPO investor (e.g., a family office) holds shares through a trust. Under Listing Rule 10.04, if the trust is deemed to be a “connected person” of the issuer, any subscription or placing of shares to that trust may require shareholder approval and a circular.

The HKEX’s Decision HKEX-GL94-18 clarifies that a trust holding shares on behalf of a director’s family members is a connected person. The prospectus must disclose this relationship and state whether the placement was conducted on an arm’s length basis.
For a pre-IPO trust that is not a connected person, the sponsor must still confirm that the trust is not a “cash box” structure. The SFC’s 2019 Guidance on Pre-IPO Investments requires that the trust must have a genuine economic substance and that the investment was not a disguised loan or a mechanism to circumvent the public float requirements.

Post-Listing Continuing Obligations: When the Trust Changes

The disclosure obligations do not end at listing. A family trust that holds 5% or more of the issuer’s shares is subject to the Part XV of the Securities and Futures Ordinance (SFO) , which requires disclosure of changes in notifiable interests.

Changes in Trusteeship and Beneficial Interests

Under Division 2 of Part XV, any change in the trustee of a trust that holds a notifiable interest must be reported to the HKEX via the DI (Director/Chief Executive) or DI (Substantial Shareholder) forms. This includes the appointment of a new trustee in a BVI or Cayman trust, even if the underlying economic interest remains unchanged.

The trigger is a change in “the capacity in which the interest is held.” A change of trustee is a change of capacity, requiring a filing within 3 business days.
Similarly, if a beneficiary’s interest in a fixed trust changes (e.g., a child reaches the age of majority and receives a fixed share), this may constitute a change in beneficial ownership and must be reported.

The “Shadow Director” Risk for Family Trust Protectors

A less obvious post-listing obligation concerns the “protector” of a family trust. The SFC’s 2023 Guidance on Directors’ Duties and Listing Rule 3.08 on the fitness of directors have been applied to protectors who exercise significant influence over the trust’s voting decisions.

If the protector has the power to veto the trustee’s decisions on share voting or disposal, the HKEX may deem the protector to be a “shadow director” of the listed issuer. This triggers the full suite of director obligations, including disclosure of interests under Part XV, compliance with the Model Code for Securities Transactions, and potential liability under the SFO for insider dealing.
In a 2024 enforcement case, the SFC successfully argued that a protector who instructed a trustee to vote against a board resolution was acting as a de facto director, and fined him HKD 3 million for failing to disclose his interest in the shares.

Practical Implications for Structuring Pre-IPO Trusts

Given the regulatory density, the structuring of a family trust for a Hong Kong IPO requires careful planning from the outset. The choice of trust jurisdiction and the allocation of powers between settlor, trustee, and protector directly impact the disclosure burden and the likelihood of a regulatory challenge.

The Case for the “Independent Trustee” Model

The cleanest path to a streamlined prospectus is to appoint a professional, independent trust company (e.g., a licensed trust company in Hong Kong, Singapore, or the Channel Islands) as the sole trustee, with the settlor retaining no reserved powers. This model allows the prospectus to state that the trustee is independent and that the settlor has no control over voting, reducing the risk of the settlor being classified as a controlling shareholder.

The sponsor will still need a legal opinion confirming the trustee’s independence under the relevant trust law (e.g., the Cayman Islands Trusts Act or the BVI Trustee Act).
The trust deed must explicitly state that the trustee has the sole discretion to vote the shares and that the settlor has no power to direct or remove the trustee without cause.

The “Family Office as Trustee” Trap

A common but risky structure is for the family office of the founder to act as the trustee. Under the HKEX’s 2025 consultation proposals, which are expected to be codified by Q3 2026, a family office trustee will be presumed to be a connected person of the issuer unless proven otherwise. This presumption triggers:

A requirement for a formal connected transaction waiver under Listing Rule 14A.
A full circular and independent shareholder approval for any share issuance to the trust.
A mandatory disclosure of the family office’s ultimate beneficial owners in the prospectus.

This structure is now effectively disfavored for Main Board listings, and sponsors are advising clients to migrate to an independent trustee model before filing the A1 application.

Actionable Takeaways for Sponsors and Issuers

Obtain a full trust deed and a legal opinion on control rights before the A1 filing — the SFC’s PN21 requires this as part of sponsor due diligence, and the HKEX will reject a prospectus that lacks this analysis.
Assume the settlor is a controlling shareholder unless the trust deed explicitly and irrevocably transfers voting discretion to an independent trustee — this is the default position under LD76-4 and GL89-15.
File a DI notice within 3 business days of any change in trustee or beneficiary interest — failure to do so is a strict liability offence under Part XV of the SFO, with maximum fines of HKD 1 million per breach.
Avoid a family office or protector with veto powers over share voting — the SFC’s shadow director doctrine now applies to protectors, creating personal liability and additional disclosure obligations.
Structure pre-IPO trust investments as genuine, arm’s length placements with independent legal advice — the HKEX’s 2019 guidance on pre-IPO investments requires the sponsor to confirm the trust is not a “cash box” or a connected party transaction in disguise.
